Description

Technical Field

[0001] This utility model relates to the field of concrete production equipment technology, and in particular to a liftable, parallel-connected concrete confluence and feeding device with two mixers. Background Technology

[0002] In existing concrete production systems at batching plants, a single mixer is typically used for mixing and feeding. Because the mixer's mixing cycle is fixed and the feeding speed is limited, problems such as slow feeding speed, long waiting times for tank trucks, and low production efficiency often occur when the mixing volume is large or when tank trucks are being loaded in concentrated batches.

[0003] Especially in the production or continuous supply of large components for wind power hybrid towers, a single mixer cannot meet the demand for rapid and continuous discharge. Although increasing the number of mixers can increase production capacity, without a reasonable dual-mixer combined discharge device, the discharge from the two mixers will interfere with each other or fail to achieve uniform distribution, resulting in concrete waste or poor discharge. Therefore, there is an urgent need for a device that can achieve synchronous discharge and rapid confluence distribution from two mixers to improve discharge efficiency and reduce tanker waiting time. This device needs to ensure the normal operation of the existing concrete conveying hopper on the production line conveyor track; therefore, it needs to be designed as a liftable, parallel-connected dual-mixer concrete confluence and discharge device.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1:

[0036] Please see Figure 1 - Figure 6 This embodiment provides a liftable parallel concrete feeding device with two mixers that can be connected in parallel to improve feeding efficiency. The specific idea is as follows:

[0037] A liftable parallel concrete mixing and discharging device for dual mixers includes a discharge port 1. The liftable parallel concrete mixing and discharging device for dual mixers also includes a chute 2 and a connecting component.

[0038] Among them, two sets of chutes 2 are provided on the outer side of the bottom of the discharge port 1. The two sets of chutes 2 are arranged in an inclined and symmetrical manner, which can guide the material to flow quickly to the designated discharge position, effectively avoid material accumulation, and improve the continuity and smoothness of concrete conveying. Connectors are provided on the outer side of the top of the chutes 2, which can adjust the position of the chutes 2 in the vertical direction to adapt to receiving equipment or construction scenarios of different heights.

[0039] As some examples, in this embodiment, the connector includes a tapered feed cylinder 201 and a conveying track 202.

[0040] The bottom inner side of the discharge port 1 is fixedly connected to a conical discharge cylinder 201. Its conical structure can gather and guide the concrete conveyed by the dual mixers. The top inner side of the steel beam is equipped with a conveying rail 202, which provides a stable installation carrier and motion guide path for the subsequent lifting drive components. The bottom outer side of the chute 2 is equipped with a hinge 203. The chute 2 is rotatably connected to the conical discharge cylinder 201 through the hinge 203. This hinge structure allows the chute 2 to flexibly adjust the tilt angle around the hinge 203 to adapt to different discharge height and conveying distance requirements.

[0041] Meanwhile, a hook plate 204 is fixedly connected to the outer side of one end of the chute 2, and an electric hoist 205 is installed on the lower surface of the conveying track 202. A hook 206 is fixedly connected to one side of the electric hoist 205. The chute 2 is connected to the hook 206 through the through hole opened in the hook plate 204. With the lifting power of the electric hoist 205, the vertical position of the chute 2 can be precisely adjusted to meet the material receiving height requirements under different construction scenarios, and greatly improve the adaptability of the device.

[0042] Furthermore, the top opening of the chute 2 is located directly below the discharge port 1. The discharge port 1, chute 2, and conical discharge cylinder 201 are connected, ensuring that concrete material can flow smoothly from the discharge port 1 through the conical discharge cylinder 201 into the chute 2, achieving unobstructed conveying. In addition, a vibrator 213 is installed on the outer side of one end of the chute 2. The vibrator 213 can generate high-frequency vibration, effectively preventing concrete from sticking to the walls or clumping due to changes in slump within the chute, ensuring the uniformity and smoothness of material conveying, and further improving the stability of the discharge operation.

[0043] Example 2:

[0044] Please see Figure 1 - Figure 6 This embodiment provides a liftable parallel concrete mixing and feeding device with two mixers that can enhance the fixing effect. The specific idea is as follows:

[0045] A liftable parallel concrete mixing and discharging device for dual mixers includes a discharge port 1, and the liftable parallel concrete mixing and discharging device for dual mixers also includes a limiting component.

[0046] The limiting component is located on the inner side of the top of the chute 2.

[0047] As some examples, in this embodiment, the limiting element includes: a circular hole 207 and a crossbar 208.

[0048] The chute 2 has a circular hole 207 on its inner top side, and a crossbar 208 is inserted into the inner side of the circular hole 207. The crossbar 208 serves as a core positioning rod, which can laterally limit the top of the chute 2. A U-shaped plate 211 is fixedly connected to the inner side of the end of the conveying track 202. The U-shaped plate 211 provides a precise installation positioning reference for the crossbar 208. The crossbar 208 passes through the inner side of the through hole at the end of the U-shaped plate 211. Through the cooperation between the U-shaped plate 211 and the circular hole 207, the crossbar 208 can effectively constrain the horizontal position of the chute 2, preventing the chute 2 from shifting left or right.

[0049] Meanwhile, a steel plate 209 is fixedly connected to the outer side of one end of the crossbar 208. The steel plate 209 can increase the force-bearing area at the end of the crossbar 208, preventing the end of the crossbar 208 from deforming due to force concentration during positioning, and also providing a stable support foundation for subsequent wedge fixing. A wedge-shaped hole 210 is opened on the inner side of the end of the crossbar 208, and a wedge 212 is inserted into the inner side of the wedge-shaped hole 210. The wedge structure has excellent self-locking performance. After the wedge 212 is inserted into the wedge-shaped hole 210, a strong frictional force is generated by the tight fit between the wedge 212 and the hole wall, which firmly locks the position of the crossbar 208, thereby achieving stable fixing of the chute 2.

[0050] Working principle:

[0051] When using this device, after the two mixers have mixed the concrete, it is discharged from the two discharge ports 1. The concrete flows through the chute 2 and converges at the position of the conical discharge cylinder 201. The tanker truck waits to receive the concrete directly below the conical discharge cylinder 201. A vibrator 213 is installed on one side of the chute 2 to facilitate the tanker truck's receiving of the concrete and prevent the concrete from adhering to the inner walls of the chute 2 and the conical discharge cylinder 201. At the same time, one side of the conical discharge cylinder 201 is welded to the steel beam of the discharge port 1. The lower end of the chute 2 is connected to the conical discharge cylinder 201 by a welded hinge 203. The chute 2 can rotate around the hinge 203 by rotating the hinge 203. A hook plate 204 is vertically welded to the upper outer wall of the chute 2. 4. The hook 206 of the electric hoist 205 is connected, and the spatial position of the chute 2 can be moved up and down by controlling the electric hoist 205. The electric hoist 205 is located on the steel beam on the conveying track 202. Symmetrical round holes 207 are opened at the upper part of the chute 2 for passing through the crossbar 208. A steel plate 209 is welded to one end of the crossbar 208, and a wedge-shaped hole 210 is opened at the other end for locking the connection between the crossbar 208 and the chute 2. Two U-shaped plates 211 are welded to the inner side of the end of the conveying track 202. The U-shaped plates 211 are connected to the round holes 207 opened at the upper part of the chute 2 through the crossbar 208. After the connection is completed, the wedge 212 is inserted into the wedge-shaped hole 210 to lock it, so as to ensure that the chute 2 will not fall from the height.

[0052] This liftable, parallel-type dual-mixer concrete confluence and discharge device boasts advantages of high efficiency, low cost, and strong adaptability. The dual mixers discharge material through discharge port 1, which then flows through chute 2 to the conical discharge cylinder 201. Combined with the vibrator 213, it effectively prevents concrete adhesion and blockage, significantly improving discharge efficiency and achieving a continuous and stable concrete supply. The electric hoist 205, hook 206, and hook plate 204 allow for flexible adjustment of the chute 2's spatial position. The hinge 203's rotation function, and the locking structure of the crossbar 208 and U-shaped plate 211, eliminate the need for additional transfer equipment to accommodate different height tanker trucks, reducing equipment investment and manual transfer costs. Simultaneously, the wedge 212, inserted into the wedge hole 210, locks the crossbar 208, and the steel plate 209 provides a limiting effect, preventing the chute 2 from falling from a height and ensuring operational safety. The entire device can be quickly adjusted according to on-site construction conditions, adapting to different concrete discharge requirements, significantly improving construction flexibility and adaptability, and facilitating efficient project progress.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
